二．機(jī)床主要性能和結(jié)構(gòu)特點(diǎn)

1．本機(jī)床系三軸數(shù)控弧齒錐齒輪銑齒機(jī)，即搖臺運(yùn)動（X軸），工件主軸運(yùn)動（Y軸）、床鞍進(jìn)給運(yùn)動（Z軸）。

   三軸均可實(shí)現(xiàn)數(shù)控軸控制和聯(lián)動。刀盤的旋轉(zhuǎn)（S軸）速度由變頻電機(jī)控制實(shí)現(xiàn)無級調(diào)速。

2．本機(jī)床搖臺和工件箱部件均采用高精度雙導(dǎo)程蝸輪副傳動，并采取了多項(xiàng)增強(qiáng)結(jié)構(gòu)剛性和傳動剛性的措施，

   保證了本機(jī)床加工精度并提高了機(jī)床生產(chǎn)率和使用壽命。

3．本機(jī)床裝有刀傾角為30°的刀具主軸傾斜機(jī)構(gòu)，不但可加工最小傳動比為2.5：1的半滾切主動輪，

   而且能實(shí)現(xiàn)更好的輪齒接觸區(qū)修正。

4．本機(jī)床調(diào)整無需更換掛輪，減少了機(jī)床調(diào)整時(shí)間。

5．本機(jī)床采用數(shù)控設(shè)定的進(jìn)給運(yùn)動，簡化了用戶操作并有利于提高切齒效率。

6．機(jī)床的數(shù)控系統(tǒng)，主要電氣、液壓元件、軸承和密封件均采用優(yōu)質(zhì)進(jìn)口件，從而保證了機(jī)床的可靠性。

7．本機(jī)床配置獨(dú)立密封的電氣控制柜，可選配空調(diào)或熱交換器。

8．本機(jī)床可配置安全防護(hù)罩和自動排屑器。

1. Main Usage of Machine

On this machine, many cutting methods can be adopted for roughing and finishing Spiral Bevel, Zero Bevel and Hypoid Gears up to 500mm in diameter and 12 mm in module. The machine is most suitutable for batch production or mass production of driving pinions of gear pairs used in cars, light and medium-sized trucks and construction machineries.

2. Main Features and Structural Characteristics of Machine

1. The machine is designed to operate as a three axes CNC control Spiral Bevel Gear Generator, i.e. cradle oscillation (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis). Each of three axes will be separately or simultaneously controlled. The rotation of cutter spindle (S axis) is controlled by an AC frequency variable motor for its stepless control.

2. A high precision dual-leads worm gear set is used for cradle drive and work spindle drive respectively, and many measures are adopted for improving the structural and driving rigidity of machine, so as to ensure the machining accuracy, productivity and operating lifes.

3. A cutter tilt mechanism with maximum tilt angle 30°is designed for the cutter spindle for cutting the pinions to mesh with non-generated gears (minimum gear ratio 2.5:1) and getting better tooth bearing correction.

4. There are no any change gears on the machine for minimizing the setting time of machine.

5. The feeds of machine are controlled by CNC programme, so as to simplify the operation and increase the cutting efficiency.

6. CNC control system, main electrical and hydraulic components, critical bearings and sealings are fine quality imports, which guarantee the machine reliability.

7. The machine is equipped with an independent sealed electrical cabinet, which is with air conditioner or thermo exchanger.

8. Safety guards and auto-chip conveyor can be provided on the machine.
